NERVE

Lightweight super-resolution / restoration. Drop an image, pick a model, press Upscale, and download the full-quality PNG.

What is NERVE? A small (~1.8M params) pure-convolution network built for ease of use, not benchmark chasing: one file, one variant, and a checkpoint that converts cleanly to dynamic ONNX, TensorRT and ncnn — no fused/unfused pairs, no headaches.

  • 2x / 4x release → for clean images.
  • 4x OTF GAN → for degraded images (blurry, noisy, JPEG-compressed).

Models, ONNX/ncnn files, training configs and the architecture live at huggingface.co/Phips/NERVE.
